The Bio-absorbable Internal Fixation Plates and Screws Tester is a specialized mechanical testing device designed to evaluate the performance of bio-absorbable orthopedic implants. It measures properties such as bending strength, torsional stability, and pull-out resistance of plates and screws used in internal fixation. This tester simulates physiological loading conditions to ensure that implants can withstand mechanical stresses during healing, providing critical data for product development, quality control, and regulatory compliance in orthopedic applications.
Standard
(1)YY/T 0509-2009 (China): Specifies mechanical testing protocols for orthopedic plates/screws made of hydrolyzable polymers, including axial pull-out, torsion, and 4-point bending tests.
(2)ASTM F2502-17 (International): Defines methodologies for evaluating the structural integrity of bioabsorbable fixation devices under physiological loading.
(3)ISO 13779-4: Additional compliance for in vitro degradation testing of resorbable materials.
Product Advantages
(1)Multi-Modal Testing: Single platform for axial pull-out, torsion, and 4-point bending tests.
(2)Biodegradation Simulation: 37±1°C pH-controlled water bath with real-time conductivity monitoring.
(3)High-Resolution Sensors: 0.001 N force/0.001 Nm torque resolution for fragile polymer testing.
(4)Modular Fixturing: Self-centering clamps accommodate plates (20–100 mm) and screws (2.0–4.5 mm).
(5)AI-Powered Analytics: Machine learning predicts degradation-induced strength loss over time.
(6)Regulatory Compliance: Pre-loaded YY/T 0509/ASTM F2502 protocols with automated reporting.
Product Features
(1)Electromagnetic Servo Actuator: 5 kN axial/1 Nm torsional capacity with programmable load ratios (R=0.1–10).
(2)4-Point Bending Fixture: Anatomical curvature adapters replicate physiological stress patterns.
(3)Dynamic pH Control: 37±1°C water bath with pH 5.5–8.0 adjustment for degradation studies.
(4)High-Resolution Imaging: Built-in 5MP camera system for crack/corrosion analysis.
(5)Safety Suite: Emergency stop, chemical-resistant enclosure, and leak detection.
(6)Touchscreen Interface: Intuitive controls with pre-loaded ASTM/YY test sequences.
